The aim of this study was to examine the effect of a theory-based in-home family intervention (In control: No alcohol!) on adolescent alcohol cognitions via its putative mediators using a randomized controlled design. In the South Holland region of the Netherlands, a total of 213 children (11-12 years) and their mothers were randomly assigned to the prevention program (108 dyads) and the control condition (105 dyads). Mediation effects were analyzed using pretest and two follow-up measurements (5 and 12 months after baseline). A path model was estimated (using Mplus) to examine the effect of the intervention on the putative mediators (frequency- and quality of mother-child communication, rules about alcohol, establishing a nondrinking agreement, and parental monitoring of the child's whereabouts). Outcomes were adolescents' perceived harmfulness of drinking and intention to drink. Multigroup analyses were performed to examine potential differences across gender. The program led to an increase in frequency of alcohol-specific communication, nondrinking agreements, and parental monitoring. Moreover, adolescents in the experimental condition perceived drinking to be more harmful and had less intention to drink compared to adolescents in the control condition. The effect of the program on adolescent alcohol cognitions was significantly mediated through having more frequent conversations about alcohol, yet only among boys. Although results on actual drinking need to be added, findings indicate that this relatively inexpensive, easy-to-administer home intervention is promising.
本研究旨在通过基于理论的家庭干预措施（对照：不饮酒！），采用随机对照设计，通过其假定的中介因素来检验对青少年酒精认知的影响。在荷兰南荷兰地区，共有213名儿童（11至12岁）及其母亲被随机分配到预防项目组（108对）和对照组（105对）。使用前测和两次随访测量（基线后5个月和12个月）分析中介效应。估计了一个路径模型（使用Mplus）来检验干预对假定中介因素的影响（母子沟通的频率和质量、关于酒精的规定、达成不饮酒协议以及父母对孩子行踪的监控）。结果是青少年对饮酒的感知危害和饮酒意愿。进行多组分析以检验性别间的潜在差异。该项目导致了关于酒精的特定沟通频率、不饮酒协议和父母监控的增加。此外，与对照组的青少年相比，实验组的青少年认为饮酒更有害，饮酒意愿更低。该项目对青少年酒精认知的影响通过更频繁地谈论酒精而得到显著中介，但仅在男孩中如此。尽管需要补充实际饮酒情况的结果，但研究结果表明这种相对廉价、易于实施的家庭干预措施很有前景。
